7.9 Operation with inverter/converter: the use of this electronic equipment as control and regulation unit, must be studied
very carefully in order to verify that it doesn't produce electromagnetic interferences or induced currents which can reduce the
safety standard required by the ATEX norms in reference to the zone in which the equipments are working.
In any case, the following conditions must be respected:
- it is compulsory to use the inverter Danfoss VLT FC202 (ex VLT8000) serie or more recent models with better performances;
- it is compulsory to set the inner commutation frequency of the inverter at maximum 4 kHz or at the minimum
frequency admitted by the inverter;
- it is compulsory to equip the inverter with the correct battery of filters, between inverter and the motor, for the
reduction of [dv/dt];
- it is compulsory to use the inverter only in the modulation range 35 - 60 Hz.
7.10 The standard maximum ambient temperature is 40°C. A maximum ambient temperature of 60°C can be accepted on
request and following tests by Caprari S.p.A. This temperature will be indicated on the rating plate of the electric pump.
